Descriptive statistics of climate variables.

<p>Descriptive statistics of climate variables: Annual mean; coefficient of variation of annual means () and coefficient of variation of monthly values () of precipitation (pre); potential evapotranspiration (pet); minimal, mean and maximal temperatures (respectively tmn, tmp and tmx); daily temperature amplitude (dtr); soil water content (swc); vapour pressure (vap); cloud cover (cld); and extraterrestrial solar radiation (sol). Coefficients of variations (standard deviation divided by the mean of the variable) of monthly climate time series are computed over the period of the CRU data (1901–2009). <i>^a</i> Globale Ecological Zone defined by FAO <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092337#pone.0092337-FAO1" target="_blank">[55]</a>; TAr: Tropical rainforest; TAwa: Tropical moist deciduous forest; TAwb: Tropical dry forest; TM: Tropical mountain system; and SCf: Subtropical humid forest.
